PLATE FOR SECURING WEATHERPROOFING.

Specification of Letters Patent.

Application filed April 2, 1913. Serial No. 758,289.

To all whom it may concern Be it known that I, CHARLES J. CARROLL, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Plates for Securing Weatherproofing, of whichthe following is a specification.

This invention relates to an improved sealing and securing plate or cleat and has particular reference to a metal cleat for securing sheets of prepared weather-proofing material upon buildings.

The main object of the invention is to provide an improved a construction of sheet which a driven heade fastening may be passed to secure it against the weatherproofing material and also having an endless sealing means extending entirely about the securing means to form an endless seal and prevent water working under the plate from any side where it would be shielded from the sun and'wind and cause injury to the weatherproofing material.

The inventive idea may be carried out in various ways but the accompanying drawing discloses several examples of devices em- 1 bodying the invention, wherein,

Figure 1, shows a series of connected plates forming a continuous strip and each nail receiving perforation of the strip being bound by its separate and distinct endless sealing means. Fig. 2, illustrates the metal strip in longitudinal section. Fig. 3 shows an enlarged cross-sectional detail through one of the plates. Fig. 4:, illustrates an enlarged sectional detail through a board; the weatherproofing material; the plate and also shows a" nail driven through the plate and pressing the endless sealing projection into sealin contact with the weatherproofing material. Fig. 5 shows a top plan view of one of the plates of a rectangular form, and Fig. 6, illustrates acircular plate embodying the invention.

Referring particularly to Figs. 1 and 2, of the drawing it will be noted that the metal strip, 1, has a seriesof crosswise indentations or grooves, 2, at regular intervals apart-thereby weakening the strip at the indentations or grooves and practically producing a series of connected. plates, 3. At the opposite ends of each crosswise roove or indentation the longitudinal side e ges oi the strip has V-shaped notches, 4:, so that a ready separation of the plates of the strip side walls.

(perforation through may be eifected'at any of the grooves or indentations.

Each plate of the strip has a central raised portion, 5, with a preferably flat upper surface, 6, from which downwardly and outwardly-inclined walls, 7, and, 8, extend. In the forms of devices shown in Figs. 1 to 5 the inclined walls, 7, are longitudinal side walls while the Walls, 8, may be considered end walls because they connect the so-called A flange, 9, extends laterally and horizontally from around the central raised portion, 5, and in the rectangular form of plate this horizontal flange is present. at both sides and both ends of the raised portion and bounds said raised portion but said flange has position in a horizontal plane below the upper surface, 6, of the said raised portion. An endless sealing projection, 10, is also provided on each plate or on the strip so as to entirely surround or bound each raised portion whereby to form an endless seal with the weatherproofing material all around the said raised portion, as will hereinafter be more fully explained.

The sealing projection, 10, is preferably located at the base of the inclined walls of the central raised portion for reasons presently to be explained but it maydep'end from the lowermost side of the plate below Patented July '3, 1914.

F ig. 4, by driving a nail, 12, through a suitable opening, 13, in the central portion, will cause the nail head 14, after the latter seats on the surface, 6, of the central ortion, to embed the endless sealing projection around each nail opening in the weatherproofing material and by making a continuous or endless seal effectually prevent water from working beneath the central portion of th plate from any side.

By referring to Fig. 4, it will be noted that the nail, 12, will first pass through the opening, 13, in the central portion of the plate, then through the weatherproofing material and finally into the wood structure, 15, against which the material, 11, is laid, and the pull of the nail-head on the central "portion of the plate will be transferred through the inclined Walls to the sealing projection, 10, to embed the latter in the material. By therefore locatin the sealing projection atthe base of the inclined walls substantially the direct action of a hammer blo'w on the nail head, 14:, afterthe head seats on the central raisedportion will be transferred through the inclined walls to the sealing projection and the location of the projection at the base of the raised portion ispreferable for this reason although not essential.

way around the throu h.

*In Fig. 6, the plate, 16, is shown as having 7 a circular form but it nevertheless embodies the features of the invention because it has a nail hole, 17; an endless recessed portion, 18, on the. upper side which produces a corres onding' endless sealing projection on the un er side so as to encircle the central portion and nailhole and form a seal all the point where the nail passes Having thus described my invention what I claim and desire to secure by Letters Patent is f 1-. A securin cleat for weatherproofing material comprlsing a single-thick platehavvas ing a central ortion' with'an exposed nailreceivi'ng per oration therein and a lateral flange portion which bounds the central portion; and said-plate havin an endless sealing projection on the under side thereof between the central portion and the rim edge of'the lateral flange portion, which endless sealing projection extends entirely around the central portion and the perforation therein and projects below the said flange portion.

2. A securing cleat for weatherproofing material comprising a single-thick plate having a central raised ortion with an exposed nail-re'ceivin per oration therein and a lateral flange which entirely bounds the said central raised portion and perforation and said plate also having a sealing prohaving a series of spaced-apart crosswise weakening indentations with a perforation in the strip between each two of said indentations and said metal strip also having a sealing projection extending below its lowermost side between each two of said indentations and each sealing-projection extending all the way around a perforation.

In testimony whereof I affix my signature in presence of two witnesses.
